Bustier

"Abustier(alternatelybustiere)
is an article ofclothingforwomen,
which is form-fitting and is traditionally worn aslingerie.
It looks somewhat like aBasque,
but a bustier is shorter. It reaches down only to the ribs or the waist and has
a different function: its primary purpose is to push up thebustby
tightening against the uppermidriffand
forcing the breasts to move up, while gently shaping the waist. A modern bustier
is often made with mesh panels rather than boning. The bustier is a
multi-purpose garment and doubles as a push-up bra for inner wear and as a
camisole for outer wear. The bustier can also be worn as a half-slip under
diaphanous upper garments if a bold display of the midriff is not desired."
